abstract = {In recent years, the number of computer science students has steadily risen, but the time for educators to give feedback to the students remains the same. Because of this predicament, many systems for the automatic or semi-automatic assessment of student tasks were developed. A fundamental problem of this development is that most of these assessment systems deploy a different type of data representation, which leads to a lack of interoperability between the approaches. This hinders the reuse of teaching materials that need to match the targeted system, leading to situations in which instructors need to recreate their materials. In this work, we aim to close this gap by introducing a model-driven approach called Assisted Assessment. The approach uses a technology-independent assessment model to bridge instructors' and assessment systems' technical spaces, helping instructors to transform their material for various systems. We introduce Assisted Assessment by describing the scenario of an undergraduate course for software technology and how the approach can help to manage the different available assessment systems.},

abstract = {Even though model-driven engineering reduces complexity during the development of self-adaptive systems and models@run.time enables using them during runtime, connecting models to different external systems still involves manual work. Those connections are essential to the complete system, as they enable external systems to react to changes in the internal model and vice versa. In our case, the model is based on Relational Reference Attribute Grammars, an extension of Attribute Grammars to enable conceptual models at runtime while retaining their benefits of modular specification and an incremental evaluation scheme. We present an approach to enable concise specification of the causal connection and needed transformations to match required formats or semantics. To show its applicability, a case study showing the coordination of multiple industrial robot arms using models is presented. We show that using our approach, connections can be specified more concisely while maintaining the same efficiency as hand-written code. The artefact comprising all source code and an executable version of the case studies is available at https://doi.org/10.5281/zenodo.7009758.},

Given the prolific results during these years, the current outcomes need to be sorted and classified. Furthermore, many gaps need to be categorized in order to further develop the research topic by experts of the research area but also newcomers. Accordingly, the paper discusses the principles and requirements of models@run.time and the state of the art of the research line. To make the discussion more concrete, a taxonomy is defined and used to compare the main approaches and research outcomes in the area during the last decade and including ancestor research initiatives. We identified and classified 275 papers on models@run.time, which allowed us to identify the underlying research gaps and to elaborate on the corresponding research challenges. Finally, we also facilitate sustainability of the survey over time by offering tool support to add, correct and visualize data.",

abstract = {Mobile autonomous robotic systems need to operate in unknown areas. For this, a plethora of simultaneous localization and mapping (SLAM) approaches has been proposed over the last decades. Although many of these existing approaches have been successfully applied even in real-world productive scenarios, they are typically designed for specific contexts (e.g., in-vs. outdoor, crowded vs. free areas, etc.). Thus, for different contexts, different SLAM algorithms should be used. In this paper, we propose a feature-based classification of SLAM algorithms and a reconfiguration approach to switch between existing SLAM implementations at runtime. By this, mobile robots are enabled to always use the most efficient implementation for their current contexts.},

abstract = {The systematic analysis of related work is an important part of every research project. Surprisingly, especially in computer science, this activity is typically performed manually. Whilst in other disciplines fully automated analysis approaches exist, the lack of a reasonably complete, queryable and free-to-use literature catalog for computer science requires computer scientists to manually retrieve, merge and analyze literature from different catalogs. Although manual literature retrieval is enforced by the current main publishers, tool support to merge and cleanse literature found in different catalogs as well as to analyze the results is possible and needed. The systematic literature review toolkit, an Eclipse Rich Client Platform application leveraging the Eclipse Modeling Framework, aims to provide this support. Currently, four main features are supported: simple literature filtering, design of a taxonomy, classification of literature and analysis of the classification by generated diagrams. The tool is available online: https://github.com/sebastiangoetz/slr-toolkit},

abstract="Distributed self-adaptive systems are on the verge of becoming an essential part of personal life. They consist of connected subsystems, which work together to serve a higher goal. The highly distributed and self-organizing nature of the resulting system poses the need for runtime management. Here, a particular problem of interest is to determine an optimal approach for knowledge exchange between the constituent systems. In the context of multi-agent systems, a lot of theoretical work investigating this problem has been conducted over the past decades, showing that different approaches are optimal in different situations. Thus, to actually build such systems, the insights from existing theoretical approaches need to be validated against concrete situations. For this purpose, we present a simulation platform to test different knowledge exchange strategies in a test scenario. We used the open source context simulator Siafu as a basis for our simulation. The described platform enables the user to easily specify new types of constituent systems and their communication mechanisms. Moreover, the platform offers several integrated metrics, which are easily extensible. We evaluate the applicability of the platform using three different collaboration scenarios.",

Incremental Runtime-generation of Optimisation Problems using RAG-controlled Rewriting

@inproceedings{sgab2016,
title = "Incremental runtime-generation of optimisation problems using RAG-controlled rewriting",
abstract = "In the era of Internet of Things, software systems need to interact with many physical entities and cope with new requirements at runtime. Self-Adaptive systems aim to tackle those challenges, often representing their context with a runtime model enabling better reasoning capabilities. However, those models quickly grow in size and need to be updated frequently with small changes due to a high number of physical entities changing constantly. This situation threatens the efficacy of analyses on such models, as they lack an efficient management of those changes leading to unnecessary computation overhead. We propose applying scalable, incremental change management of runtime models in the presence of a complex model to text transformation. In this paper, we present and evaluate an example of code generation of integer linear programs. In our case study using synthesized models, we saved 35 - 83% processing time compared to a non-incremental approach. Using our approach, future self-Adaptive systems can handle and analyze large-scale runtime models, even if they change frequently.",

abstract = {Role-based modeling has been investigated for over 35 years as a promising paradigm to model complex, dynamic systems. Although current software systems are characterized by increasing complexity and context-dependence, all this research had almost no influence on current software development practice, still being discussed in recent literature. One reason for this is the lack of a coherent, comprehensive, readily applicable notion of roles. Researchers focused either on relational roles or context-dependent roles rather then combining both natures. Currently, there is no role-based modeling language sufficiently incorporating both the relational and context-dependent nature of roles together with the various proposed constraints. Hence, this paper formalizes a full-fledged role-based modeling language supporting both natures. To show its sufficiency and adequacy, a real world example is employed.},

However, today's mobile applications often do not consider energy requirements and users lack information on their energy consumption before they install and try them. In this paper, we compare mobile applications from two domains and show that they reveal different energy consumption while providing similar services. We define microbenchmarks for emailing and web browsing and evaluate apps from these domains. We show that non-functional features such as web page caching can but not have to have a positive influence on an application's energy consumption.},

Hence, ICT applications are optimized to provide the best possible user satisfaction for the least possible energy budget. An inevitable prerequisite for such optimizations is the ability to analyze software's energy consumption. In consequence, many energy profiling frameworks have been developed. The problem we address in this paper is that profiling frameworks are device- and application-specific and, hence, cannot be reused. We analyze the key requirements of energy profiling frameworks and propose a generic framework reusable for different devices and applications, designed according to these requirements. We evaluate the presented framework using two case studies showing the reusability in two significantly different scenarios.},

abstract = {A widespread business model in cloud computing is to offer software as a service (SaaS) over the Internet. Such applications are often multi-tenant aware, which means that multiple tenants share hardware and software resources of the same application instance. However, SaaS stakeholders have different or even contradictious requirements and interests: For a user, the application's quality and non-functional properties have to be maximized (e.g., choosing the fastest available algorithm for a computation at runtime). In contrast, a resource or application provider is interested in minimizing the operating costs while maximizing his profit. Finally, tenants are interested in offering a customized functionality to their users. To identify an optimal compromise for all these objectives, multiple levels of variability have to be supported by reference architectures for multi-tenant SaaS applications. In this paper, we identify requirements for such a runtime architecture addressing the individual interests of all involved stakeholders. Furthermore, we show how our existing architecture for dynamically adaptive applications can be extended for the development and operation of multi-tenant applications.},

abstract = {SUMMARY Software is changed frequently during its life cycle. New requirements come, and bugs must be fixed. To update an application, it usually must be stopped, patched, and restarted. This causes time periods of unavailability, which is always a problem for highly available applications. Even for the development of complex applications, restarts to test new program parts can be time consuming and annoying. Thus, we aim at dynamic software updates to update programs at runtime. There is a large body of research on dynamic software updates, but so far, existing approaches have shortcomings either in terms of flexibility or performance. In addition, some of them depend on specific runtime environments and dictate the program's architecture. We present JavAdaptor, the first runtime update approach based on Java that (a) offers flexible dynamic software updates, (b) is platform independent, (c) introduces only minimal performance overhead, and (d) does not dictate the program architecture. JavAdaptor combines schema changing class replacements by class renaming and caller updates with Java HotSwap using containers and proxies. It runs on top of all major standard Java virtual machines. We evaluate our approach's applicability and performance in non-trivial case studies and compare it with existing dynamic software update approaches. Copyright © 2012 John Wiley \& Sons, Ltd.},

abstract = {Dynamic software updates (DSU) are one of the top-most features requested by developers and users. As a result, DSU is already standard in many dynamic programming languages. But, it is not standard in statically typed languages such as Java. Even if at place number three of Oracle's current request for enhancement (RFE) list, DSU support in Java is very limited. Therefore, over the years many different DSU approaches for Java have been proposed. Nevertheless, DSU for Java is still an active field of research, because most of the existing approaches are too restrictive. Some of the approaches have shortcomings either in terms of flexibility or performance, whereas others are platform dependent or dictate the program's architecture. With JavAdaptor, we present the first DSU approach which comes without those restrictions. We will demonstrate JavAdaptor based on the well-known arcade game Snake which we will update stepwise at runtime.},

To develop software w.r.t. its energy consumption, testing is an essential activity, since testing allows quality assurance and thus, energy consumption reduction during the software's development. Although first approaches measuring and predicting software's energy consumption for its execution on a specific hardware platform exist, no model-based testing approach has been developed, yet. In this paper we present our vision of a model-based energy testing approach that uses a combination of abstract interpretation and run-time profiling to predict the energy consumption of software applications and to derive energy consumption test cases.},

Such applications impose two basic challenges: (1) the complexity of specifying collaborative behavior and (2) the need for a flexible and lightweight communication infrastructure for mobile robot teams. To address these challenges, we introduce NaoText, a role-based domain-specific language for specifying collaborative robot applications. It contributes dedicated abstractions to conveniently structure and implement collaborative behavior and thus, addresses the complexity challenge. To evaluate NaoText specifications, we introduce an interpreter architecture that is based on (REST) as a lightweight and flexible infrastructure for communication among robot teams. We exemplify the application of NaoText using an illustrative example of robots collaborating in a soccer game and discuss benefits and challenges for our approach compared to state-of-the-art in robot programming.",

For each purpose various solutions with different specializations

the engines have to be adopted. In this paper, we want to show how
a workflow engine can be designed to support different workflow languages
and different domains - an extensible multi-purpose workflow engine.
Our approach for this kind of engine is based on a workflow net engine
that allows us to support most of the existing workflow languages.
To support different tasks of different specifications, we integrated
object roles in our engine. This extension of the object-oriented
paradigm allows flexible runtime adaptations and extensions. Thus,
we are able to add new domain specific functions to our engine at
runtime, even if the original process language does not support them.},

of large applications, and many companies have already decided to
use the cloud for their infrastructures. An enterprise IT infrastructure
often includes a workflow management system. In a cloud, various
workflow engines can coexist, each with its specific functional responsibility.
A central instance is in charge of distributing process fragments
without causing high technical or economic costs. The derivation
of cost functions, the determination of the fragments to be executed
on the respective engines with minimal costs, is a complex issue,
especially if various processes have to be executed simultaneously.
This paper approaches the problem of delegating an entire process
to a distributed infrastructure and shows how it can be solved efficiently
with neural networks. To ensure computation performance when handling
various neural networks, we use the MapReduce framework. The distributed
computation capability of MapReduce can help process the mass of
training data generated by system monitoring in the networks. So,
the performance usage in the central instance is decreased and the
entire system is able to scale with the growing infrastructure.},

abstract = {Delegation is an important design concept in object-oriented languages. In contrast to inheritance, which relates classes to each other, delegation operates on the level of objects and thus provides more flexibility. It is well known, that usage of delegation imposes performance penalties in the sense of delayed execution. But delegation on the level of sourcecode is optimized on bytecode level up to a degree, that imposes much lower performance penalties than expected. This paper examines in detail how big these penalties are.},

abstract = {Maintenance of a software framework often requires restructuring its API (refactoring). Upon framework upgrade structural API changes may invalidate existing plugins - modules that used one of its previous versions. To preserve plugins, we use refactoring trace to automatically create an adaptation layer that translates between plugins and the framework. For each encountered refactoring we formally define a comeback - a refactoring to construct adapters. Given an ordered set of refactorings occured between two framework versions our tool ComeBack! executes the corresponding comebacks and yields the adaptation layer.},

abstract = {Although the API of a software framework should stay stable, in practice it often changes during maintenance. When deploying a new framework version such changes may invalidate plugins - modules that used one of its previous versions. While manual plugin adaptation is expensive and error-prone, automatic adaptation demands cumbersome specifications, which the developers are reluctant to write and maintain. Basing on the history of structural framework changes (refactorings), in our previous work we formally defined how to automatically derive an adaptation layer that shields plugins from framework changes. In this paper we make our approach practical. Two case studies of unconstrained API evolution show that our approach scales in a large number of adaptation scenarios and comparing to other adaptation techniques. The evaluation of our logic-based tool ComeBack! demonstrates that it can adapt efficiently most of the problem-causing API refactorings.},
